Question

Identify the logic operation carried out by the following circuit.

• A. AND
• B. NAND
• C. NOT
• D. OR

Hint:

Remember that a NAND gate is essentially an AND gate followed by a NOT gate, i.e., the output is the negation of an AND operation.

Answer 1

The Correct Option is B

- The circuit consists of two AND gates. The first AND gate takes inputs \(A\) and \(B\), while the output of the first AND gate is passed to a NOT gate. The NOT gate inverts the output of the AND gate.
- Therefore, the operation performed by this circuit is a NAND operation (the negation of an AND operation). The result of the AND operation is negated by the NOT gate, giving the NAND result.
